Pati Jagung, Kitosan, Plasticizer, sorbitolAbstract
Bioplastik polimer dapat terurai oleh aktivitas mikroorganisme di dalam tanah. Pati jagung, kitosan dan plasticizer sorbitol dapat dimanfaatkan sebagai bahan pembuatan bioplastik. Penelitian ini bertujuan untuk mengetahui pengaruh terhadap mutu sifat fisis bioplastik. Variasi campuran pati jagung dan kitosan (A) 40% : 60%, (B) 50% : 50% dan (C) 60% : 40% dengan plasticizer sorbitol 2 ml. Dengan uji ketebalan, biodegradasi, dan daya serap air. Hasil data pengujian ketebalan sampel A sebesar 0,24 mm, sampel B sebesar 0,17 mm dan sampel C sebesar 0,16 mm. Nilai biodegradasi sampel A sebesar 33,3%, sampel B sebesar 50% dan Sampel C sebesar 80% dan daya serap air sampel A sebesar 25%, sampel B sebesar 30% dan sampel C sebesar 50%. Nilai biodegradasi sudah memenuhi standar SNI 7188.7:2016 pada sampel C. Sedangkan daya serap air belum memenuhi standar ASTM D570-98 pada semua sampel.
